Amarillos
The Arroyo de Los Amarillos project area is located immediately north of Barrick's Pascua Lama concessions, extending northward along the Argentina-Chile border. Los Amarillos hosts a number of colour anomalies visible on satellite imagery near the Barrick concession boundary. These were recognized by other operators to be epithermal alteration zones and hence the focus of nearly all previous exploratory work. It appears that less than 10% of the concession area has been mapped or explored, in part due to the difficult terrain. Because of the challenging terrain and poor access, only limited prospecting was carried out by Malbex in the 2008/2009 field season.
In addition to the +17 million ounce Pascua Lama gold deposit to the south, Yamana is exploring immediately to the east of the Los Amarillos concessions, and Barrick continues to control the exploration concessions on the Chilean side of the border to the west.
The 2009/2010 field season at Los Amarillos began by removing obstructions and improving access roads to allow re-investigation of the zones of hydrothermal alteration identified on surface to date, including geophysical surveying (magnetometer and CSAMT). The effectively unexplored remainder of the property is being evaluated by property-wide stream sediment sampling, prospecting, geological mapping and rock sampling. Diamond drilling will be conducted in the subsequent field season if warranted by the mapping, sampling and geophysical results.
